How to bin

 

It seems that the SB-E has the exact same OC characteristics like the regular Sandy Bridge, including the infamous clock wall. It's not as easy to find the clock wall as with Sandy Bridge, but here's a guide that will be able to give you information on your sample's maximum overclock.

 

Under discussion again ...

 

FYI, I found there is a way to bin the CPU on air. I tested it with this CPU and it worked like I expected. What you need to do:

 

- go in bios and set all VRM config like you'd do for extreme OC

- run 2c2t (to save heat)

- set vcore to 1.55~1.6V

- set bclk to 100

 

Now, increase the CPU ratio. In the beginning, you will be able to boot straight in to OS. After a while, it will crash at OS loading (for W7, it will lock at the ball swinging moment), but when pressing the reset button, the board will reboot. This means it can run this frequency with better temps! Once you lock and pressing reset doesn't work, you've found the maximum frequency of your CPU.

 

In my case, I could always reset from lock-up upto 55x. With 56x, I could not reset and had to power off the entire setup. The end result was 5510MHz for my CPU under LN2.

Anyone found a good way to quickly bin these chips?

 

It seems that the SB K-sku routine is no longer applicable (at least no on this board) as the turbo multplier only kicks in when actually entering the operating system and no longer when the boot options are being shown. So, no blinking cursor anymore. Also, it seems that the chips really need colder temperatures to show the max CPU OC capability ~ 0°C.

 

With low temperatures binning should be relatively easy (NickShih mentioned 1 per 5 minutes), but not on air anymore.

its an MSI GD65 8D (thanks to your thread about the board ive managed to get it to 5ghz a few minutes ago:) temp wise im getting 22-25 idle and 63-69 load. I have to figure out how to mount my ss on this board so I can try what will this chip do under sub zero.... still a terrible chip that requires 1.625v for 5 ghz....

Does it really need that 1.625V?

 

With that little trick, it should be running "normal" voltage range.
